[. . . ] Place, possible to bear the unit, where vibration and noise are not increased. Place, where discharged wind and noise do not cause a nuisance to the neighbors. Place, where a distance marked is available as illustrated in the above figure. Power Source Before inserting power plug into receptacle, check the voltage without fail. The power source is the same as the corresponding name plate. [. . . ] When bending, be careful not to crash pipes. Connect beforehand the indoor/outdoor electric cable, and then pull out the connected to the heat insulation of connecting part specially. Fixing the indoor unit body Hang surely the unit body onto the upper notches of the mounting plate. Move the body from side to side to verify its secure fixing. In order to fix the body onto the mounting plate, hold up the body aslant from the underside and then put it down perpendicularly. 4. Connecting the indoor/outdoor Electric Cable Removing the wiring cover Remove terminal cover at right bottom corner of indoor unit, then take off wiring cover by removing its screws. When connecting the cable after installing the indoor unit 1. Insert from outside the room cable into left side of the wall hole, in which the pipe has already existed. Pull out the cable on the front side, and connect the cable making a loop. 4 Indoor unit When connecting the cable before installing the indoor unit Insert the cable from the back side of the unit, then pull it out on the front side. Loosen the screws and insert the cable ends fully into terminal block, then tighten the screws. Pull the cable slightly to make sure the cables have been properly inserted and tightened. After the cable connection, never fail to fasten the connected cable with the wiring cover. Note: When connecting the cable, confirm the terminal number of indoor and outdoor units carefully. If wiring is not correct, proper operation can not be carried out and will cause defect.

Easily-demount cleaning of indoor unit 1. Top inlet can be taken down Open the inlet grille, press the claw of the clip on the unit, then take down the top inlet. (according to figure 1) 2. Vertical flap can be taken down Overturn the vertical flap, press the claw of the clip , then take down vertical flap. (according to figure 2) 3. Horizontal louvers can be taken down After taking down vertical flap. Horizontal louvers are appeared, draw the middle louver, and take down the horizontal louvers .

Connection of pipes To bend a pipe, give the roundness as large as possible not to crush the pipe , and the bending radius should be 30 to 40 mm or longer. Connecting the pipe of gas side first makes working easier. The connection pipe is specialized for R410A. Half union Flare nut Forced fastening without careful centering may damage the threads and cause a leakage of gas. Pipe Diameter ( ) Fastening torque 18N. m 40N. m 55N. m Liquid side 6. 35mm(1/4") Gas side 9. 52mm(3/8") Spanner Gas side 12. 7mm(1/2") Torque wrench Be careful that matters, such as wastes of sands, etc. If it is over 5m, the function of the unit will be affected. If the pipe has to be lengthened, the refrigerant should be charged, according to 20 g/m. But the charge of refrigerant must be conducted by professional air conditioner engineer. Before adding additional refrigerant, perform air purging from the refrigerant pipes and indoor unit using a vacuum pump, then charge additional refrigerant. 3. Connection Use the same method on indoor unit. Loosen the screws on terminal block and insert the plugs fully into terminal block, then tighten the screws. Insert the cable according to terminal number in the same manner as the indoor unit. If wiring is not correct, proper operation can not be carried out and controller may be damaged. [. . . ] After flaring work again and vacuumize, fill up prescribed refrigerant from the gas cylinder. 2-way valve HSU-22HV03/R2(DB) HSU-22HVA103/R2(DB) 2-way valve 3-way valve 6 Detach the charge hose from the service port, open 2-way valve and 3-way. Turn the valve rod anticlockwise until hitting lightly. 6 6 3-way valve 7 To prevent the gas leakage, turn the service port's cap, the valve rod's cap for 2-way valve and 3-way's a little more than the point where the torque increases suddenly. 8 After attaching the each caps, check the gas leakage around the caps.
